Slope definition
Slope gradient is the angle of inclination of the soil surface from the horizontal. It is expressed in percent, which is the number of feet rise or fall in 100 ft. of horizontal distance.

- B- 1.3 Excavations Made in Type C Soil 1. All simple slope excavations 20 feet or less in depth shall have a maximum allowable slope of 1 1/2:1 Simple Slope. 2.All excavations 20 feet or less in depth which have vertically sided lower portions shall be shielded or supported to a height at least 18 inches above the top of the vertical side.
- Factor of Safety for a Cohesive Soil Slope: The soil slope can be either dry or submerged or seepage may occur parallel to the slope. These cases are considered in the following subsections: 1. Factor of Safety for a Dry Cohesive Soil Slope: Factor of safety against shear failure is given by – Thus, the factor of safety for cohesive soil.
(c) Requirements- (1) Soil classification. Soil and rock deposits shall be classified in accordance with appendix A to subpart P of part 1926. (2) Maximum allowable slope. The maximum allowable slope for a soil or rock deposit shall be determined from Table B-1 of this appendix. (3) Actual slope. (i) The actual slope shall not be steeper than the maximum allowable slope.

Importance of slope
Slope gradient is important because it influences the rate at which runoff flows on the soil surface and erodes the soil. Slope shape (straight, concave, or convex) and slope length are also important properties of soil surfaces.

Measuring slopeType C Soil Slope Ratio
In soil evaluation, two stakes will be set up to indicate where slope is to be determined. A slope finder is used to measure slope. (As shown in the picture) Measure slope to the nearest degree from the top of one stake to the top of the other, Determine the slope classes according to table shown.
